Embodiment Construction

[0022] The present invention will be further described below in conjunction with specific examples.

[0023] One, the preparation method of product of the present invention comprises the following steps:

[0024] 1. Dispersion: Put n-heptane and xylene into the cylinder, stir with a disperser, and add synthetic rubber while stirring until the solution is clear and transparent; continue to add gas phase silica and pigments while stirring, and increase the speed of the disperser to Disperse at 2000 rpm for 30 minutes and then move to the grinding area for grinding.

[0025] 2. Grinding: Use a grinder to grind the color paste several times until the fineness is qualified. During the grinding process, the temperature of the color paste is controlled at 50-60°C, and ≥75°C is not allowed.

[0026] 3. Dilution: Throw the milled color paste into the remaining component solvents to dilute, then disperse evenly with a disperser, adjust the viscosity of the material liquid to a qualifi...

Abstract

The invention provides a tearable spray film and a preparation method thereof. The spray film is prepared from 5-10% of synthetic rubber, 5-15% of n-heptane, 20-40% of a naphtha solvent, 5-10% of xylene, 1-5% of butanone, 2-9% of heptanon, 0.5-1.5% of pigment, 0.1-0.5% of fumed silica and 30-50% of dimethyl ether. The spray film has proper adhesive force and good flexibility and can be torn off and stripped from an object in flake; besides, bubbles and pits are not likely to be formed due to coloring uniformity and smoothness, and a substrate or an original color is not corroded or damaged due to the mild formula.

Description

technical field [0001] The invention relates to an easy-peeling film type spray paint. Background technique [0002] Modern people pursue a fashionable and changeable life, and like to change the color of cars, furniture or electrical appliances. [0003] In particular, with the improvement of people's living standards, cars are no longer luxury goods, and car beauty is a very popular industry nowadays, and body color change is a hot spot. Because of its easy operation and various colors, aerosol paint has become the first choice for many car players to change the color of the car body, especially the color change of the wheel hub. [0004] However, traditional spray paint is mostly attached to the color-changing object through chemical bonds, and has strong adhesion to the substrate. Generally, it is difficult to remove and replace after the color is formed. The man-hours required for color change are very large and cumbersome. Moreover, the solvents of traditional paints...
